Description
Very powerful parameterized monster projectile attack pointer. Can be used to create standard attacks or angular spreads, with or without homing. Can fire missiles at a customized height, and can optionally chain to another state when the object is within melee range of its target, allowing situational attacks like those used by the Imp, Baron, and Cacodemon. The melee parameter should be set to -1 unless a valid frame name is provided, otherwise the object will disappear forever on melee. It's almost never desirable to leave melee in its default value.
Homing missiles must also have the SEEKERMISSILE flag set and a homing maintenance pointer (e.g. Tracer, GenTracer, HticTracer) in their frames.
Usage
MissileAttack(name, type, zofs, aofs, melee)
Parameters
- name = Name of thing type to fire (no default, must be valid)
- type = Select homing property (default of 0 = 0)
- 0 or normal = will not home
- 1 or homing = may home
- zofs = Amount to add to standard z missile firing height (32 units, default of 0 = 0, can be negative)
- aofs = Amount to add to actor angle in degrees (default of 0 = 0, can be negative)
- melee = Frame state to enter for optional melee attack (default of 0 = 0: will disappear; negative values = no melee attack)
Examples
This is a line from a Decorate state definition of a spiderdemon lookalike, that fires a BFG9000 projectile:
SPID H 4 Bright A_MissileAttack(BFGShot, normal, 0, 0, -1)
Notes
No particular notes.
